"While operating with the Russian Northern and Pacific Fleets, the nuclear-powered ballistic missile submarine Ryazan accomplished combat missions and launched ballistic missiles under the program designed to check the preparedness of naval strategic nuclear forces," the press office said.

As representatives of Russia’s defense and industrial sector said earlier, the Project 667BDR nuclear-powered ballistic missile submarine Ryazan was expected to re-enter service with the Pacific Fleet before the end of 2015.

The Project 667BDR nuclear-powered ballistic missile submarine is designed to destroy the enemy’s strategic facilities. It can also launch torpedoes to fight surface and underwater targets.

The Project 667BDRM nuclear-powered submarine is armed with 16 intercontinental ballistic missiles of various types, as well as four nose-based 533mm torpedo systems.
